Argh, looks like I missed something important in testing: a WARN from
check_early_ioremap_leak.  Looks like moving the reclamation of the EFI
memory map that late makes check_early_ioremap_leak figure that it won't
get reclaimed at all.

As far as I can tell, ioremap won't work that early; EFI really does
need to use early_ioremap.  Since at the moment we don't seem to have
any other drivers that need to access boot services memory, any
objection to moving efi_free_boot_services back to just after ACPI?
